I'm curious what you're comparing the engine noise to? I ask because our 2025 Pilot Elite with the J35Y8 engine definitely sounds different than older vehicles with port injection or older technologies. I suspect a lot of what I hear are the high pressure fuel pump and injectors, but can't really say.
We moved from a 2022 Audi Q5 to the Pilot, as I wanted long-term reliability. Definitely a downgrade in comfort. When driving home from the dealership (about 100 miles), I thought something was wrong with the transmission. Either it's smoothed out in the past year and 16k miles, or I've become accustomed to how it feels. Unless we forget, we now only drive in Sport or Tow modes. This does two things: 1) turns off the auto start/stop, and 2) prevents the VCM system from activating. In either mode, the transmission doesn't hunt for the correct (most efficient?) gear continuously. Sport mode holds the gears longer than Tow mode at slower speeds. Play with each to see what you like.
This afternoon I swapped out the winter tires/wheels used on our winter trips to Wisconsin with the OEM Bridgestone Alenzas. The winter setup are 265/60R18 vs the OEM 255/50/R20. The Bridgestones feel as harsh as a work truck/van with load range E tires at max air pressure. Absolutely feel horrible compared to the Continental Viking Contact 8s. I'd put Continental DSW06+ on the Audi and they had a much smoother ride and higher grip than the OEM Continentals that came on it. I want to swap out these Bridgestones, but my wife just retired and has asked I wait a bit and get a little more use out of them. Maybe in the next day or two when she goes back out on the Bridgestones, she'll have a different opinion.
